1'0 all ulmm it- 'moy onu/cm'n:

Be it known that LJonx 'lnonsox. d ra per, restdlng at lnverr'argdl. I\r- \\""/ealand. have invented ccrtain new and useful .lmpro'vt Within the tire secured to tire rim, :1 series of transverse hook-ended snbstantiallyflat springs laid side by side to form the circumforenoe, pair of these springs being required to extend transrerselr round the tire. a rubber or flexible OOVLIZHQ, and a tread solution'ed to tire covering with. an elastic sub- Stance between. the tread and tii-e covering.

Tile springs of tires oi ti e class described heretofore made are liable to break in. the middle.

A leading feature of tl 's invention is the construct-ion wherein" this breakage is '1 actioally iiibriatcd. as iaeroinalter described.

intbe accompanying drawings. illustrating tilisin'vontion. Figure l is a sectional VltW oi the tire. Fig. 2 is a part View of the tire, showing the tread, a portion of t be outer cover, the wirerings in section. and the clips. Figjfi is an enlarged view oi the clips and wire rings. Fig. 4- is a view illustrating an altornatire method of connect ng tl e lioolo ended springs at t -eir upper ends. Fig. is a. segmental \icw. t re tread and outer cover being omitted.

Instead oi" transverse ilOUli-(Iitltd flat springs extending transvcrselv in one piece from one curved edge of the run to tee otncr and which are litllJlQ to break t zere is :1 pair of similar luiolq-endcd springs l '2. one end it of eaoir ei igaging the curved edge -l oi tne rim and the other ends ti 7 being connected in any suitable manner. Titus tli se ends 6 to engage each other, and a link may be slipped over them to hold them togctlzcnpr oatl1 of the ends 6 7 may be constructed wzt'n a book 9, adapted to book over one oi two Wire rings 10 ll. which are constructed to run round the l'iigliest part of the tare. and 111 this case between eacb. pair oi" springs 1 l a llOl(-GI1(lQ(l clip 12 is rings l0 11 together.

Combined with t re Wheel rim or folly 53 which has inwardly-ourved edges 4, there are inner supports 13 14 for the transverse flat, book-ended springs 1 2, which are bent round tlicse inner supports 13 Hand retained in place by the outward pressure of their lower ends 3 against the curved edges 4 of the rim and by the connection of their upper ends 6 7, as before described. These transverse springs 2 are of the same width and are set closely together side by side at the lower ends 23, which engage the curved edges l of the. rim 5, so as .to ill] tire wliole circumference of the rim 5, and when in place there are intervals 15 between their adjacent portions,

placed to hold the Wire tlt-ese intervals 15 being least at the curved edges 4 ol the tire-rim 5 upper ends 6 7, which tore descrilied.

when wire rings 10 1] areused, clips 12 connect them, said clips 12 liavii'ig a hollow portion 16 between their ends 17 18 to re.- ceire a. yielding composition 19, snob as twine. solutioned and wound round the oil'- cumference in said hollow portion 16 to bind the cover 20 thereto. These rings are yielding, being made up of coiled or twisted steel strands, so that when they are in place the tire may have longitudinal resiliency.

The ends 3 of tire springs l 2 engaging the curved edges 4 ol' the rim .3, have a small flange or solid portion to prevent adjacent springs riding over each other.

There is a flexible outer cover 20, with thickened edges .21, adapted to be placed over the springs l .2, so that the thickened edges 21 are introduced above the springsl 2 and under the inwardly-curved edges 4 of the rim 5 and are retained in place by the outward pressure of the springs l 2 against said curred cdg 's l of the rim 5. v

Twine it) is wound tightly round the circmnl'ercnce of t he tire above the elastic cover and beds itsell in tlie liollo'w portion 16 of the and greatest at the are connected, as tire clips which connect the wire rings 10 11 a d 7 may be constructed U-sbapcd, Fig 4-, so as bind the middle of the cover 20 seourelyto the springs. in tliccasewlieretbecndsoi the transverse springs are connected, as illustrated in Fig. 4, the twine is wound in, the U-sliaped portion thereof,

Tile tread 2'2 is solutirmcd onto the outer .rown above the yielding material or twine.

The inner supports 13; H are ex'tcndcd high enough and are formed..zwith afqurved portion corresponding to that of the gsprings 11-2, so .as to lie close to and aflordsupport thereto for some little distance and prevent side wabble thereof.

The springs 1 2 are made 'the same width throughout, and consequently when in place lie apart at'the to of the curve, and in the used.

wire rlngs are not used.

rim, means for connecting the upper ends of each pair of transverse springs, and supports secured to the tire-rim for said jsprings sub stantially as described.

- A vehicle-tire wheel comprising in combination a tire rim having inwardly-curved edges, a series of similar transverse substantially fiat springs having their lower ends hooked enga ing said curved edges. and ex tending round tire -rirn-, and, having their upper ends U- shaped and engaging each other, 'links uniting eachp'air of said U-shaped upper ends, and

supports secured to'the tire-rim for said springs, substantially as described.

3. A vehicle-tire comprising in combination atire-rim havin inwardly-curved edges, a pair of wire rings ying side by side round the tire circumference, a series of similar transverse substantially fiat springs having the whole circumference of the hooked edges and extending round the 'whole circumference ofth'e tire-rim their lower ends.

In a tire for vehiclewheels,. in combinaairs laid side by side round thewho e circum-- erence of the tire-rim, said springs having their lower ends hooked so as to, engage the curved edges of the rim and'm'eans for connecting'the upper-ends ofeach pairof springs,

substantially as and for the purposes set forth.
